The Host Galaxy of FRB 20171020A Revisited

Understand

The putative host galaxy of FRB 20171020A was first identified as ESO 601-G036 in 2018, but as no repeat bursts have been detected, direct confirmation of the host remains elusive.

• In light of recent developments in the field, we re-examine this host and determine a new association confidence level of 98%.
• At 37 Mpc, this makes ESO 601-G036 the third closest FRB host galaxy to be identified to date and the closest to host an apparently non-repeating FRB (with an estimated repetition rate limit of < 0.011 bursts per day above 10 erg).
• Due to its close distance, we are able to perform detailed multi-wavelength analysis on the ESO 601-G036 system.
